e. 3x-10=5(x-10)
f. 4x+8/5x+8=5/6​

Answer 1

Please mark as brainliest my friend it took lot of effort and time for typing

Step-by-step explanation:

x + 5 = 2x

=> x - 2x = -5

=> - x = - 5

=> x = 5 {cancelling the minus sign}

2(11x + 4x) = 750

=> 11x + 4x = 750 / 2

=> 11x + 4x = 375

=> 15x = 375

=> x = 375 / 15

=> x = 25

x/2 + 9 + 3x/8 = x

=> 8(x/2 + 9 + 3x/8) = 8x ( multiplying both side by 8 )

=> 8*x/2 + 8*9 + 8*3x/8 = 8x

=> 4x + 72 + 3x = 8x

=> 7x + 72 = 8x

=> 72 = 8x - 7x

=> 72 = x

=> x = 72

10x = x + 54

=>10x - x = 54

=>9x = 54

=> x = 54/9

=>x = 6

3x - 10 = 5(x - 10)

=> 3x - 10 = 5x - 50

=> -10 + 50 = 5x - 3x

=> 40 = 2x

=> 2x = 40

=> x = 40/2

=> x = 20
